Summit Racing Thermoquad
The one I saw was like a NASCAR 3 bbl. The secondary's are a single oval venturi.
Funny you mention that.....I was looking at these at Summit and they mention "square bore" AND "spreadbore". These sure look like repop Thermoquads, don't they? But only 625 CFM...? Has anyone seen these up close or have any knowledge of them?
